To all ,whlom, it may concern Be it known that I, THEOPHILUS BRowN,

' rearward while conveying it to the field or place of spreading, and more particularly to means for holding and guidingsaid end-gate in proper position during the operation of elevating and lowering the same.

Said- 'mprovement consists of twov peculrarly-shztped arms arranged one at each slde of the cart, preferably inside of and next to the side-boards of said. cart, one end of each arm being ivoted to its respective sideboard, and t e other end to the lower part of the ends-gate, which is preferably made in two horizontal parts, 'ivoted to ether, vthe purpose of said arms b ei g, as aforesaid, to properly hold and guide said end-gate when elevated or lowered by the usual rod-and-lever mechanism controlled by a lever at one side of the drivers seat. By the employment of said holding and'guide arms the usual grooved guides on the Sideboards for guiding said end-gateare dispensed with, as will be hereinafter more fully set forth.

In the drawings, Figure 1 represents a side view of a manurespreader with my improved end-gate attachment a plied thereto. Fig. 2 is a vertical longitudi the rear end of the spreader, showing my irn proved holding and full lines in the position it occupies when the end gate is in its lowest position and by dotted lines when said end-gate is partly elevated. Fig. 8 is a similar sectional view to Fig. 2, showing the end-gate and holding and guide attachment in their most elevated positions, being the positions which they occupyduring the operation of spreading the manurc Fig. 4 is a perspective view of partbf the end-gate and cart and my aforesaid attachment, and Fig. 5 is an enlarged" lan of part of the rear end of the spreader, s owing my attachment applied thereto.

Referring to my resents the body of the cart'; a=B,'itsmovable present drawings,.A- repbottom; C, the transverserotary beater, D

which D, the end-gate,

inthisfins'tance. is

made in two parallel horizontal sections of about equal width and ivoted to' E-is a crank-lever pivoted at tionary bearing the cart and-attached to the end of the upper edge of the upper board D ofthe end-gate. Said crank-lever E is also pivoted to the usual rod G, connected with the operating-lever H at one side of-the drivers seat I, and J is my im roved attachment, which is made in the form of a goose-shaped arm in side view, as is shown in the drawin s. It is. designed in practice to use one of t ese arms u on each side of the cart just inside of the si e-boards thereof in about the posit-ion shown in Fi 5;

but I do not'limit myself to this'num er. For the urpose of convenience I will deoneof them. One end thereofthe. rear endis erably to the lower board D just above its horizontal center, audits forward endis pivoted to the side of the cart at J v The arm- J is slotted at J for a short distance longitu dinally at said pivot to perinitof the longitudinal movement thereof, so that it may automatically adjust itself to the irregular swinging movements of the par s when the end gate is elevated or lowere this provision being n'ecessitated by said end-gate being supported atthree pivotal points, J, J and F.

The bottom board I)" of the end-gate being pivoted to the top board D and :the' arm J pivoted to said bottom "board and to the side-board of the cart results in'a peculiar swinging movement of the attached parts when the crank-lever E is'operated to elevate or lowerthe end-gate.

The parts are constructed and arranged to ether at a.- to a sta- F" on each side-board A" of 5 pivoted to the end-gate, prefoperate in practice as follows: When the lever E commences to elevate or draw up the end-gate, the arm J forces the lower section D away from and relieves'it from the pressure of the load, and as the end-gate is continued to be drawn upward itismoved in a curved line outward and conforming to the radial movement of the arm J on its fulcrum J- and 'is therefore lifted without friction from the load, at the same time holding the upper part of said load in position frombeing' forced onto the upper part of the rotary I beater;

v .is between the beater and the bottom edge ofv 'In my patented manure-spreader previously referred to guides are employed on the sides of the cart or holding the end ga'te'in osition in. lifting andlowering the same.

hese are liable to become clogged,'so that said end-gate is moved with difficult and to overcome this objection and provi e'a. way of liftin and lowering the same more easily and Wit out-friction 1s the main purpose of my inv ention.

travels in practice in the direction from front to rear, thereby carrying the body of manure placed thereon toward the rear or end gate,

and the" rotary beater 0 turns, as is shown by the arrows, toward the front at the bottom and toward the rear at the top thereof, thereby causing its teeth 0- to discharge the manure over the same between it"and the bottom of the adjustable end-gate, said teeth in the revolution of the beater tearing through the closely-packed manure and breaking it up preparatory .to bein discharged from the spreader. Naturally t. e smaller the space the end-gate the finer it will be pulverized in passing through by the teeth of the beater on account of its confined condition between it and the end-gate.

The de ree of said pulverizationiof the manure in ischarging it from the spreader is regulated by len' thening or shortening the rod G by its turn uckle G, so as to lower or raise the end-gate, and thus decrease or increase the space between the bottom ofsaid end-gate and the ends of the rotary beater- ,pins C, as aforesaid, and when rocks or any other hard substances in the manure come in contact with the bottom of the end-gate the latter automatically yields and allows the same to pass through without injury to the parts, owing to the slots J formed-in the arms J, which permit the latter to be forced back loiigitudinally by said rocks or other larger substances in assing through.

1 do not of course imit myself to the exact shapes or positions of said arms J J. Any

The movable bottom '13 of the spreader similar attachment connected at one end with the cart-body and the other end with a hinged end-gate may be employed within the scope of my mventionto' accomplish the same result, said end-gate, made in hinged sections, being, it is thought, a new feature in a manure-spreader or other vehicle-of a similar nature. I

, Having now described said invention,what I claim therein as new, and desire to secure byLetters Patent, is

1. In a manure-spreader, an end-gate formed of two pivoted sections, means for raising and lowering said end-gate attached to the upper of said sections, and an arm with one end pivotally attached-to a station.- ary bearing and with the other end pivoted to the lower section of the end-gate, whereby the path of the movement of said lower section is determined independently of. the means of liftingsaid endate. a

2. The combination 0 vthe cart-body, its

, hinged end-gate D D, and the lifting-lever E attached to the upper part of said end-gate,

with the arm J pivoted at one end to said cart-body and at its other end to the bottom part of the end-gate, substantially asset forth.

3. In a manure-spreader, an end-gate formed of two pivotedsections, means for raising and lowering said end-gate, and means for yieldingly guidmg the lower of said sections in. a path independent of the path of then per section.

.4. in a manurespreader, an end-gate formed of two pivoted sections, means for raising and lowering sa'id end-gate, an arm with one end pivoted to the lower section offormed of two pivoted sections, means for raising and lowering said end-gate, and means for guiding the lower of said sections in apath inde orcester, Massachusetts, August 9,1904.
